Running a sample round that produces information
A sample round is not a free sample programme. Each sample costs production time, and suppliers who give unlimited free samples to every enquirer eventually serve the buyers who convert. A structured round respects that and gets better information in return.
Give all shortlisted suppliers the same brief, the same artwork file, the same product specification and the same deadline. Identical inputs are what make the outputs comparable, and a supplier who asks for a private conversation about their strengths before quoting has already told you something useful about how they will handle an open process.
Score four things on the sample, not on the relationship. First, specification adherence: does the sample match the stated product, colour and placement dimensions. Second, print quality and hand feel: inspect seams, registration, ink coverage, edge quality against the artwork at arm length, and wash behaviour if the specification includes a wash requirement. Third, finishing: is it folded correctly, tagged, sized and packed the way the brief asked. Fourth, turnaround: when the sample arrived relative to when it was promised.
Handle samples physically, not photographically. A photograph flattens colour and hides hand feel, which is precisely what distinguishes one decoration process from another. Where a specification names a corporate colour, compare the physical sample against the physical standard under a neutral light rather than trusting a screen.
Then require the sample supplier to state what they would change for production and what would stay the same. That single question separates suppliers who understand a sample as a prototype from those who understand it as a courtesy. It also surfaces the suppliers who produced the sample on a different machine or a different product line than they would use at volume, which is the most common way a good sample becomes a disappointing run.
